I have a minimally invasive foraminotomy w/on fusion scheduled for Jan 6th. I'm having very severe pain in front right thigh, knee, back and hip. Problem is apparently foraminal stenosis at exiting L3 nerve root. Dr. says it's mainly ligamentum flavum hitting the nerve. About an hour procedure with excellent prognosis for leg pain relief. Dr. is less certain that it will help with the back pain but he said fusion may not help there either. Another doctor wouldn't do the endoscopic procedure but wanted to do a fusion. If I think about it I'll let you know how it goes or you can reach out. Merry Christmas and Happy New Year!
